AUTOMATIC CIRCUIT MAKER AND BREAKER.

To all whom it may concern Be it known that 1, MAX ScHoLL, a subject of the Emperor of Austria-Hun ary, residing at Houston, in the county of arris and State of Texas, have invented certain new and useful Improvements in Automatic Circuit Makers and Breakers, of which the following is a specification.

This invention relates to new and useful improvements in an automatic circuit maker and breaker.

The object of the invention is to provide a device of the character described which includes a mechanism in connection with electrical conductors, whereby at stated intervals the circuit through said conductors is completed and likewise broken.

With the above and other objects in view the invention has particular relation to certain novel features of construction and opspecification and illustrated in the accompanying drawings wherein Figure 1 is a side elevation of a clock with the improved device shown in connection therewith. Fig. 2 shows a rear view thereof. Figs. 3, 4 and 5 show detail views of detached parts of the device. Fig. 6 shows an end view of the part shown in Fig. 3, and- Figs. 7 and 8 show side and end views respectively of a collar employed in the device.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral l'refers to a clock of ,the ordinary and well known construction. Any form of chronometer, however, may be employed, as may be found most practical.

The numeral 2 designates the hour hand post of the clock which rotates with said hand, performing one rotation each hour. The rear side of the clock casing has an orifice 3 alined with the post 2 and a cylindrical block 4, of non-conducting material fits in said orifice and is secured on the rear end of said post and fixed to the block 4 and projecting. outwardly therefrom is the stud 5, square in cross section. A stub shaft 6 is provided whose" inner end has a socket 6', square in cross sectional. view and in which the stud 5 fits, the inner end. of said shaft being split forming jaws which have a 'certain amount' offlexibil-ity,'causing them to grip said stud. The'shaft 6, in the main, is of uniform diameter-buthas an enlarged section 7 beyond which is the blank, neck 8.

Specification of lctters'latent.

Application filed June 5, 1914. Serial No. 843,195.

This shaft is formed of brass or some other good conductor and surrounding the blank neck 8 is the collar 9 which is rotatable independent of the shaft, and is formed of brass or some other good conductor and is in constant contact with the shaft 6. Threaded over the outer end of the shaft 6 and abuttlng against the section 7 is a sleeve 10 formed of non-conducting material and the extreme outer end of the. shaft carries the sleeve 11 formed of conducting material. The section 7 and the sleeveslO and 11 are of uniform diameter and are exteriorly threaded from end to end, the thread of each of these parts forming a continuation of the thread of the adjacent part. As shown in Fig. 1 there are two end sections formed of conducting material and an intermediate section formed of non-conducting material, but it is obvious that the number and relaas desired.

Fixed to the clock 1 at some desirable place is a cylindrical casing 12 which surrounds a coil spring 13. One end of the casing has a bearing in which a short shaft 14 fits. The inner end of this shaft is secured to one end of the pull spring 13 and the other end of saidspring is secured to the tive lengths of these sections may be varied opposite end of the casing'12. One end of a rod 15 is pivoted to the outer end of the shaft 14 and the other end of this rod is formedinto a hook 16, the free end of the hook being flattened and formed into a blade whose edge rests between the threads of the section 7 and the sleeves 10 and'll. The hook 16 isseparated from the rod 15 by means of a non-conducting section 17. This rod rests against the adjacent end of the casing 13 as a fulcrum and the pull 0f*tlie spring 13 holds the .hook 16 yielda-bly in contact with the parts carried by-the shaft 6, it is apparent that the hook will travel in an arc and consequently the rod 15 should be elbowed out, as shown in Fig. 1, a suflicient distance to remain in contact with the parts 7, 10 and 11, thropghou-t [their entire length. This device is designed particularly for the purpose of automatically cutting oil the The circuit is completed'to the light through the wire 18, col1ar 9, section 7 hook 16 and wire 19. It is obvious that the shaft 6 pering fixedto said-mechanism, a pull-spring forms a complete rotation each hour and as i't rotates the hook 16 will movealong totimes may be accurately fixed when the cir- 5 cuit will be completed and broken, the same v being determined by the'number of threads carried by the conducting and nonconducting sections of the shaft 6., when the hook 16,

reaches the outer end of section 11, it may i then be manually replaced at the starting point. I I

The block 4 and the section 17, both of non-conducting material, insulate the clock from the electrical currentand the movement 1 of said clock'is not afi'ected by said currentl- What I claim is 1.
